The tilting device of the presentinvention is designed? to'tilt and unloadtransferandstorage bins such. as those disclosed in my copending application Serial No. 74,623,

entitled Shipping Container, filed December '8, 1960.

'Thus the bin will comprise sides including a side legs 22; a top'24; a discharge door 26 which is .hingedly,

connected with'the top 24; and afill' hole cover 28.:

The tilting apparatus comprises'afloorrhaving two channels 30 which are preferably provided with inwardly coverging side Walls32; The purpose of the inwardly converging side walls 32 in that if the legs, 22 are not lowered properly relative to the center-line of the channels 30, the bin legs 22 will be urged because of the weight of the binand. the walls'32 centrally crosswiseof'the floor.

Carried by the truss members 34 and thus rotatable with the moving parts of the tilt rack are spaced apart piston and cylinder means 60 and spaced apart movable piston rods62. Thepist'on rods 62carry a yoke or hold down'means64 which hold down means engage the top 86 which will operate through a suitable port 88 in the hopper 78 and thus the door can be permitted to move toopen position and the contents of the bin discharged into the hopper 78 with sealing relation around the edges of the door and the opening in the hopper.

A stop 90 is provided with a mating alinement with door 26 (when in open position as shown in FIG. 5)

and thus the door functions to cover port 88 whenjthekey 86 is removed.

As shown in connection with FIGS. '4 and Set the drawings, the limitingstop 80, which is adjustable, will support the bin for longitudinal movement relative to the braces 36 when desired. a

As the bins may be of the structure disclosed in US. Letters PatentNo. 2,648,428 and have flexible sides, the bins may belly out and thus need support intermediate the edges of a side 20. Tracks 68 are carried by the truss members 34; Rollers 70 are mounted for traveling movement on tracks 68. A dolly 69 is supported by rollers 70 and the bin supporting plate 72 is adjustable toward and away from dolly 69 by adjusting screws 76. The plate 72 is designed to support the bellying or mid-portion of a'bin side which may belly out, as is best taught by said Patent 2,648,428. Limitstops 74 are provided to determine the maximum extent of travel of the rollers 70 in-either direction on tracks 68. The amount of belly in a particular bin or the extent thereof will of course depend upon the weight of the material in the bin' and hence the reason for the adjusting screws 76 so that theamount of load carried by theplate 72 and the rollers 66 can be determined.

In the form of my invention disclosed in FIGS. 1 to 7,

it is desired to discharge the contents of the bin against afixed hopper, such as hopper 78, and'have a sealing engagement with the top of the bin around the discharge door 26 and with suitable gasket means 84 on said hopper 78. Also I provide an adjustable stop 80 which is carried by the turning portions of the tilt rack and which will function as a fine adjustment to limit maximum turning movement of the turning parts of the tilt rack in one direction as is best illustrated in FIGS. 4 and 5 of the drawings.

In operating the structure of this form of my invention as illustrated in FIGS. 1 to 7 inclusive, the bin is loaded with the legs 22 in the channels and leaving the space 82 (see FIG. 1) between the wall 20 of the bin and the V braces 36. Next the device is rotated an amount such as 15 as it best illustrated in FIG. 3 of thedrawings, and the rotation is sufi'icient so that the legs 22 slide down the channels 30 and the bin moves towardthe left,as indi- I 72. At this time the clamping device 58 is operated so that the yoke 64 engages with the top 24 of the bin and the relative size and position of said yoke is such that there is no interference with the manipulation of the door 26 nor the fillhole cover 28.

Once the bin is clamped so there can be no relative longitudinal movement of the bin, the bin may be rotated to the position shown in FIGS. .4 and 6 of the drawings.

Now the clamping mechanism 58 is released and the bin 5 Willslide lengthwise from the position shown in FIGS.

4 and 6 of the drawings to that shown in FIGSf-S and 7 or from the full line position to. the dash line position shown in FIG. 4 of the drawings. The gasket'84 is carried by the hopper 78 and thus the bin slides lengthwise into da sealed relation betweenthe bin and'the discharge hopper and hence hopper 112 may be a barrel or ahopper.

sealing position against said gasket andthesizeof the l I or :any desired place the discharge'can flow without sealed opening in the hopper 78issuch that the door may be unlatched afterthe gasket'84 is'in sealing position around the door 26.

In FIG. 5 of the drawings Ih'ave shown a key: member provide for precise alining before the clamp means 58 movesto open position and thus a very precise fit obtains and thus eliminates loss of material.

plane 72, limit tracks 68, dolly 69, rollers 70, bin support stops 74, and adjustable screws 76.

Furthermore in FIGS- 8, 9 and 10, there is illustrated a combination clamping structure and discharge spout numbered generally 96. This member 96 may be operated intoand out of clamping and unclamping positions by piston and cylinder means and piston rods 62 similar to the constructions of FIGS. 1 to 7 inclusive. In the structure of FIGS. 8 to 10 inclusive, the piston rods 62 are pivotally connected with a hopper. 98. Hopper 98 is movable toward and away from the bin and may be urged into sealing relation around the door 26 of a bin with a gasket between the discharge spout around'the door 26 and against the top 24 of the bin. .The relative sizes of parts are such that the door 26 may be openedafter the combination clamping and discharge spout is in sealed position.

The mode of operation 7 and 10 in first loading, then permitting the bin to shift after approximately 15 of tilting and then clamping will be the same in connection wtih FIGS. 8, 9 and 10 as it was in connection with FIGS. 1 to 7 inclusive.

discharge spout 96and the discharge hopper 106.

Thus the principal difierences between the structure the tilting portion ofthe devicerotatively moves the device into sealed discharge relation wtiha fixed hopper 106 ratherpthan providing forthe sliding'movement which -is best depicted by a comparison between FIGS. 8, 9

arid 10'and FIGS. 6 and 7 of the'drawings. The structure illustrated inFIGS. 8 to 10 ofthe drawings canbe employed in connectionwi'th a modified 'coma biirationclamping and discharge spout. In other words, the assembly, indicated generally by 96 to .10 inclusive may be modified 'to ,form the combination clampingand discharge spout 110 of FIGS. 11 and 12.;

In the forrnbf the structure of FIGS. 11 and 12, .we are dealing with a load or bin content whichdoes not require relation to the discharging spout-from the bin. 1 J

.In the form of my invention shown in FIGS. 8, .9'and TV 10. parts which are the same as those illustrated in FIGS.-

The truss member 34 carries a cross brace 92 which? of the structure of FIGS. 8, 9

of FIGS. 8, 9 and 10over FIGS. 1-to 7 inclusive, is that the description is incorporated by reference and without repetition.

The combination clamp and discharge spout 110 is self sealing with a discharge gate 114. Thus the bin is provided with any suitable gate or cover for the discharge opening thereof which is first removed. Then the tilting part of the device is turned about as in the a other figures to permit the bin to slide on its legs. Then the clamping and discharge spout 110 is moved into sealing relation around the discharge opening in the bin.

gate may be opened at suitable times when the discharge flow of material from the bin is alined with a suitable discharge location such as the hopper 112.

From the foregoing it will now be apparent that I have disclosed a tilting device for tilting a bin having a discharge gate or opening on the top side thereof. This tilting device comprises a fixed base structure which may comprise the structural members 44 which carry a suitable bearing on which the tilting rotor assembly may be mounted such as bearings 40. The rotor assembly is U-shaped in plan thus leaving a front opening through which a bin may be loaded and a top opening in connection with which clamping devices may be operable. The rotor assembly will comprise the floor channels 30, truss members 34, braces 36 and suitable shafts mounting the rotor member for rotation such as stub shafts 38 operating within bearings 40 carried by the fixed base structure. Next suitable means are provided to rotate the rotor assembly through preferably 135 in either direction. Next clamping means are carried by the rotor assembly and either provide the type of clamp shown in FIGS. 1 to 7 inclusive, 8 to 10 inclusive, or 11 and 12.

After a bin has been loaded on the rotor assembly, then the rotor assembly is turned an amount to provide for shifting of the bin and thus positively aligning the bin relative to a clamping means or a discharge spout.

In FIGS. 1 through 10 of the drawings, the alignment is such that the bin is discharged through a fixed material receiving hopper such as 78, or 106. In FIGS. 1 through 7 inclusive, registration with the fixed hopper is pro ided by traveling movement of the bin on its side whereas registration in FIGS. 8 through loinclusive is provided by the combination clamp and discharge spout 96. form of the device shown in FIGS. 11 and 12, positive registration with a receiving hopper is not indicated.

In the form of the invention shown in FIGS. 1 to 7 inclusive, the belly of a bulging bin is supported by a.

dolly 69 whereas the edge portions of'the bin are supported by rollers 66.
